There are five levels in the Internet protocol stack as a whole. What do they mean? How much does each of these levels have to do with the other levels?

It is conceivable that both Internet Protocol (IP) and User Datagram Protocol (UDP) have the same level of unreliability. Is there a thought process behind this decision?

In favour of layered protocols, what are the two most compelling reasons to do so? An example is needed to support what you are saying.

In the Internet of Things (IoT) web stack, what function do the protocols UDP and IPV6 serve? What exactly is the difference between a sensor having a static IP address and one that has a dynamically assigned IP address?

The whole Internet protocol stack consists of five distinct layers. Just what do they imply? To what extent does each of these stages relate to the others?

Here, the distinctions between "connectionless" and "connection-based" protocols are examined.

There are two main reasons why layered protocols are used.

What are the two strongest justifications for layered protocols?

What is a protocol stack? It is a list of protocols that are utilized.

In terms of the protocol stack used by the Internet, how many layers are there in total? Is there a list of particular duties that correspond to each level that may be found anywhere?
